The first one (IFR) the tower had not received when I called for start. the second one (VFR) no trace when I contacted LATCC flight briefing, Now checking the third one (IFR) no FPL sent to the departure airfield but in the system.
On Sunday I will see what happens
Finally the big THANK YOU!!!! to the guys at LATCC for all the checking and chasing that they have done over the last few weeks.
